Abstract

1515905 Rotary harrows C VAN DER LELY NV 27 Oct 1975 [31 Oct 1974] 44209/75 Heading A1B Between each pair of driven soil working members 3 is arranged one or two freelyrotatable soil working members. In Fig. 3, each freely-rotatable soil working member 24 comprises a pair of tines 30 secured to an upright slot 25. In Fig. 5, each freelyrotatable soil working member 32A comprises a pair of discs 36 secured to a horizontal shaft 34. The freely-rotatable soil working members 24 or 32A are carried by arms 22 or 22A secured at their forward ends to vertical shafts 21 which are rotatably supported in sleeves 19, so that the members 24 or 32A are bodily displaceable about the axes b. The extent of this displacement is limited by recesses in the shafts 21 cooperating with pins 38, and spring mechanisms (not shown) may urge the arms 22 or 22A to their central positions.
